The perimeter of each face of a rubik's cube is 22.2 centimeters. what is the length of an edge of a rubik's cube? this is dividing decimals

The length of an edge of a Rubik's cube is 5.55 cm .

Step-by-step explanation:

As given

The perimeter of each face of a Rubik's cube is 22.2 centimeters.

As in the cube all the sides are of equal length .

Perimeter represented the sum of all sides.

As each face of the cube is consist of 4 sides .

Thus

Putting the value in the above

                                                                            = 5.55 cm

Therefore the length of an edge of a Rubik's cube is 5.55 cm .

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
